ROOF-FLASHING.

- Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed March 11, 1905. Serial No. 249,608.

To ctZZ whom it may concern:

Be it known that L Lewis W'ATsoN, a citizen of the United States,residing at Nashua, in the county of Hillsboro, State of New Hampshire,have invented certain new and useful Improvements in Roof-Flashings, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to a roof-flashing, and particularly to anadjustable structure adapted for roofs of difierent inclinations,whereby the stand-pipe may at all times be disposed in a true verticalposition.

The invention has for an object to provide an adjustable connectionbetween the standpipe and roof-flashing comprising spherical memberspivotally connected together, so that the roof-flange may be adjusted ininclination within the spherical cap carried by the standpipe to conformto the inclination of the roof to which it is applied and then securelyheld in position by connecting the spherical members together.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings, Figure 1 is a vertical section showing the applicationof the invention; Fig. 2, a horizontal section on the line 2 2 of Fig. 1with the cap removed; Fig. 3, adetail perspective of the base andspherical member carried thereby; Fig. 4, a similar view of the cap;Fig. 5, a perspective of the packing-ring carried by the stand-pipe; andFig. 6, a detail vertical section of the pivotal clamping connectionbetween the spherical members.

Like letters of reference refer to like parts in the several figures ofthe drawings.

The letter A designates a stand-pipe, which may be of any desiredmaterial or for any preferred purpose and which extends upward throughan opening A of an ordinary character in the roof A Upon this roof theelongated conical base B is disposed and is provided at its lowerportion with a laterallyextending flange B, adapted to rest upon theroof-timbers and to be secured thereto in any desired manner. Thisupwardly tapering base B is provided at its upper end with a sphericalmember B having a cut-away portion B formed in the top and one side wallthereof and a pivoting-aperture 13* disposed at the equator of thesphere. This pivoting portion is surrounded by a roughened or corrugatedface B", WlllCll cooperates with the cap member to secure the partstogether, as hereinbefore described. The spherical member B is alsoprovided upon the side opposite the cut-away portion B with a stop-lug13, adapted to engage the lower end of the spherical cap member C whenit is swung to its extreme of movement in that direction, and thusprevent the movement of the parts, so as to expose the cut-away portionbelow the cap 0. This cap is formed at its upper portion with a flangeO, adapted to fit the standpipe C, and at its lower edge with dependinglugs 0 each provided with a pivot-opening O and a roughened inner face0* to cooperate with the face B upon the spherical member B Under someconditions of use it is desirable to provide a packing-collar around thestandpipe, and if such be required a collar, as shown at D, may beprovided and seated at its lower portion D upon'the flange O of the cap,while the space between this collar and the stand-pipe is filled with asuitable packing material D as shown in Fig. 1.

As shown in Fig. 2, when the parts are assembled the pivoting-lugs (J ofthe cap are brought into alinement with the apertures D* of thespherical portion of the base and these parts secured together by meansof a bolt 0 supplied with an adjustable nut, so that the same acts asboth a pivot and a clamp. In the latter instance the roughened faces Band 0*, being drawn into contact with each other, securely retain thespherical members against any pivotal movement when they are in theiradjusted position. This adjustment may vary from any desired angle-forinstance, from the inclination shown in full lines in Fig. l to thatshown in dotted lines, wherein the roof is disposed upon a horizontalplane and the lug B contacts with one side of the cap to limit thetravel thereof and prevent the exposure of the cut-away portion B at theopposite side thereof.

In the operation of the invention it will be seen that the base isadapted for ready adjustment to roofs of any ordinary pitch orinclination, and when secured in position the spherical connectionbetween the parts thereof provides a broad bearing-surface to resist anystrain by wind or other pressure against the pipe, as by a sphericalstructure a maximum holding-surface disposed in the most efficientposition to resist the strain is secured. It will also be seen that thepivotal connection between these spherical members permits a readyadjustment, while they may be then clamped firmly by the roughened facescontacting with each other, and thus held against any relative movement.

It will be obvious that changes may be made in the details ofconstruction and configuration without departing from the spirit of theinvention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim,and desire to secure by Letters Patent, is-

1. In a roof flashing, an elongated upwardly-tapering base provided witha laterally-extending roof-plate at the lower portion thereof, asubstantially spherical member at the upper portion of said base, thetop and one side wall of said member being cut away, a substantiallyspherical cap secured to a standpipe and disposed to cover said cut-awayportion, and means for clamping said member and cap against relativemovement.

2. In a roofflashing, an elongated 'upwardly-tapering base provided witha laterally-extending roof-plate at the lower portion thereof, asubstantially spherical member at the upper portion of said base, thetop and one side wall of said member being cut away, a substantiallyspherical cap secured to a standpipe and disposed to cover said cut-awayportion, a pivotal connection between said cap and spherical member,roughened contactfaces upon the cap and spherical member at theirpivotal point, and a stop-lug carried by said member at one side toengage said cap.

3. In a roof-flashing, a base provided with a laterally-extendingroof-plate at the lower portion thereof,a substantially spherical memberat the upper portion of said base, the upper portion of said memberbeing cut away, a substantially spherical cap having a flange engaging astand-pipe and disposed to cover said cut-away portion, a pivotalconnection between said cap and spherical member,a packing-ringsurrounding said stand-pipe and embracing said fiange, and means forsecuring said ring upon said pipe.

4:. In a roof-flashing, a base provided at its upper portion with asubstantially spherical member having a segmentally-disposed slot in itsupper portion, a roughened face having a pivoting-aperture disposed atthe equator of said member, a substantially spherical cap disposed uponsaid member and extending to the pivotal point thereof, a depending lugcarried by said cap and provided with a roughened inner face, and aclamping-bolt extending through said lug and spherical member.

In testimony whereof I affiX my signature in presence of two witnesses.
